Saccadic Eye Movement Speed and Motor Response Execution

Abstract

This study investigated the hypothesis that systematic changes in efficiency (speed) of saccadic eye movement speed (SEMS) are accompanied by parallel improvements in associated motor responses or vice versa. Seventy-two individuals were classified according to SEMS and randomly assigned to batting practice, SEMS training, or control groups. Each of the two experimental groups practiced a total of ten hours under their respective training conditions. All individuals were pre- and posttested on batting performance. Results indicated that prior to training, individuals with faster SEMS were significantly better batters than those with slower SEMS. Training through actual batting produced significant increases in both SEMS and batting performance. Training through a SEMS program resulted primarily in significant improvements in SEMS. However, some evidence was found to indicate that observable (although less dramatic) changes also occurred in batting performance for this group.     

Parenting and Child DRD4 Genotype Interact to Predict Children’s Early Emerging Effortful Control

Effortful control (EC), or the trait‐like capacity to regulate dominant responses, has important implications for children’s development. Although genetic factors and parenting likely influence EC, few studies have examined whether they interact to predict its development. This study examined whether the DRD4 exon III variable number tandem repeat polymorphism moderated the relation between parenting and children’s EC. Three hundred and eighty‐two 3‐year‐olds and primary caregivers completed behavioral tasks assessing children’s EC and parenting. Children’s DRD4 genotypes moderated the relation between parenting and EC: Children with at least one 7‐repeat allele displayed lower EC in the context of negative parenting than children without this allele. These findings suggest opportunities for modifying early risk for low EC.     

Re-situation challenges for international students ‘becoming’ researchers

This paper presents data generated during a semester-long programme to support international students from countries in Melanesia and Asia embarking on masters research in education in a New Zealand university. All were scholarship recipients. The researcher-and facilitator-of the programme, was interested in documenting and understanding the nature of the students’ experience as they planned and wrote research proposals. The process of developing a research proposal, as one of the early stages of ‘becoming’ a researcher, highlighted a number of challenges for the six case study students. The challenges are viewed from a transition or ‘resituation’ perspective (Eraut in Stud Contin Educ 26(2): 247–74, 2004, 2008) rather than an adjustment one. A resituation perspective assumes that students brought with them “personal expertise, practical wisdom and tacit knowledge” (Eraut 2008, p. 42) which needed to be reconciled with what was demanded of them by different aspects of the research planning process. The resituation challenges experienced by the students included situating a perceived problem or issue in the research literature; reconciling personal research goals with the limitations of one’s own agency as a researcher; integrating new learning with research goals; and reconciling the new role or identity as a researcher with the previous role as colleague or community member. The paper presents a case for providing a context for postgraduate students in which explicit recognition of what they bring to the research task, and acknowledgement of the resituation challenges can take place.     

Teacher labour markets in South Africa and Botswana: A comparative analysis

This article compares key features of the labour markets for teachers across Botswana and South Africa in order to seek possible explanations for the apparently larger teacher shortages in South Africa. It is argued that South African teachers earn relatively lower wages when compared to professionals with comparable qualifications; they have also been subject to a more haphazard series of reforms in teacher training, and are the product of a teaching culture shaped heavily by powerful trade unions. The impact of these factors on both the quantity and quality of teachers is considered.     

Current Challenges in Social Work Distance Education: Responses from the Elluminati

One of the first tasks of the Social Work Distance Education Network at the Faculty of Social Work at the University of Calgary was to review the literature and address three research questions to inform policy making and planning relating to distance social work education programming. This paper is intended to disseminate responses to these questions from a small group of dedicated and experienced distance educators who have adopted the moniker Elluminati. (The Elluminati adapted their name from a popular online audio-conferencing program.) These questions include: (1) What is the optimal class size for a distance delivery offering? (2) What supports does an online course require for development and effective delivery? (3) What types of courses are suitable/unsuitable for online learning?     

Pair programming and secondary school girls’ enjoyment of programming and the subject Information Technology (IT)

This paper reports on a qualitative study that examined how pair programming shapes the experience of secondary school girls taking IT as a subject, with respect to their enjoyment of programming and the subject itself. The study involved six Grade 11 girls who were doing solo programming in Grade 10 and pair programming in their following Grade. The results showed that the girls enjoyed the subject more when programming in pairs due to improved comprehension of the task. They especially enjoyed the socialization and communication brought about by pair programming. The assistance, support, motivation, focus and encouragement they received from partners when stuck or while fixing errors made the programming experience more enjoyable for them. The increased enjoyment brought about by pair programming resulted in the perception of greater learning in the subject IT and also to greater interest in it. It also led to greater persistence in dealing with problems. Pair programming should be implemented right from the start of Grade 10 since it may lead to greater enjoyment of programming and the subject IT in general. The approach may also lead to more girls being attracted to the subject.     

Instructor perspectives of multiple-choice questions in summative assessment for novice programmers

Learning to program is known to be difficult for novices. High attrition and high failure rates in foundation-level programming courses undertaken at tertiary level in Computer Science programs, are commonly reported. A common approach to evaluating novice programming ability is through a combination of formative and summative assessments, with the latter typically represented by a final examination. Preparation of such assessment is driven by instructor perceptions of student learning of programming concepts. This in turn may yield instructor perspectives of summative assessment that do not necessarily correlate with student expectations or abilities. In this article, we present results of our study around instructor perspectives of summative assessment for novice programmers. Both quantitative and qualitative data have been obtained via survey responses from programming instructors with varying teaching experience, and from novice student responses to targeted examination questions. Our findings highlight that most of the instructors believed that summative assessment is, and is meant to be, a valid measure of a student's ability to program. Most instructors further believed that Multiple-choice Questions (MCQs) provide a means of testing a low level of understanding, and a few added qualitative comments to suggest that MCQs are easy questions, and others refused to use them at all. There was no agreement around the proposition that if a question was designed to test a low level of skill, or a low level in a hierarchy of a body of knowledge, that such a question should or would be found to be easy by the student. To aid our analysis of assessment questions, we introduced four measures: Syntax Knowledge; Semantic Knowledge; Problem Solving Skill and the Level of Difficulty of the Problem. We applied these measures to selected examination questions, and have identified gaps between the instructor perspectives of what is considered to be an easy question and also in what is required to be assessed to determine whether students have achieved the goals of their course.
